GRAIN-DOOR FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented July 17, 1906.

Application filed August 30,1905. Serial No. 276.346.

T 0 a whont it may concern:

Be it known that 1, Jonas GREEVY, a citi zen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Grain-Doors for Railway- Cars, of which the following is a specification.

This invention relates to improvements in grain-doors for railway-cars used as a means for confining grain at the doorway of the car;

It has been the custom for purposes of shipping grain to nail boards crosswise upon the inner door-casing of the car and at time of unloading to break or tear away these boards, thereby resulting in a waste of material. Various grain-doors have heretofore been presented, generally accompanied, how ever, with expensive features which would preclude their use.

The object of this invention is to provide a portable grain-door for cars effective for confining the grain, which opens outward to effect unloading and has especial reference to simplicity and cheapness of construction.

Another object is to present a grain-door having sustaining means consisting of a hingably-mounted leaf adapted to be pressed against the inner vertical wall of the car from weight of the contacting grain in a manner to resist the outward pressure of grain coming upon the opposite leaf at the doorentrance and the employment of a pair of locking-arms also sustained by pressure of the grain.

ith these and other objects in view the invention consists of certain features of construction and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.

Figure 1 in the drawings represents a perspective view of the inner side of the graindoor vertically placed and in operative position upon the inner doorway of a car. Fig. 2 is a perspective view of the outer side of the grain-door and a portion of the outer wall of the car, the parts of the door being in the same relative position as shown by Fig. 1. Fig. 3 is a plan view of the invention as exhibited by Fig. 1. Fig. 4 represents a perspective view of the outer side, and Fig. 5 of the inner side, of the invention to illustrate form and relative position of the leaves and reinforcing-plate Fig. 6 is a plan view of Fig. 5. 7 represents a perspective view of the swivel to illustrate inclined walls. Fig. 8 is a vertical side view of the swivel.

In the drawings the numeral 1 indicates the inner wall, 2 and 3 the door posts or jambs, 4 the outer wall, and 5 the door-sill, of a car. I construct a grain-door 6, having the leaves 7 and 8 substantially of the same height, secured together with hinges 9. Upon that side of leaf 8 opposite hinges 9 I rigidly mount the reinforcing-plate 10, having the arms 11 and 12. These arms are preferably constructed integral with plate 10 and are formed to extend upon the same plane as plate 10 and substantially parallel with reference to each other.

The outer ends of leaf 8 and plate 10 when mounted are coincident, and the. opposite end of plate 10 may properly be said to terminate at a, Fig. 5, and the inner ends I) and 0, respectively, of leaves 7 and 8, are joined by the hinges at a distance less than the length of plate 10, thereby providing a portion d of said plate, Figs-2 and 4, adapted to overlap the seam or lengthwise aperture 6, Figs. 1,, 41,. 5, between the inner hinged ends of these leaves. As thus constructed leaves 7 and 8 are adapted to have a hin e movement, and when positioned end to end arms 11 and 12 and the portion d of plate 10 are adapted to make surface contact upon parts of the outer side ofleaf 7. Arms 11 and 12 are po sitioned a sufficient distance from each other so that they make contact upon and near the upper and lower outer surface of leaf 7 and upon the outer side of leaf 7 in a manner to come between these arms is mounted the swivel 13, having arms 14 and 15, adapted on occasion to overlap a part of arms 11 and 12.

The grain-door, as shown, is of few parts and may be quickly constructed by any mechanic at very little expense, ordinary lumber being used. Leaf Sand plate 10 are joined by nails or screws, and upon leaf 7 the transverse strips 16 and connecting-strip 17 are generally employed, the pivot for the swivel being passed through leaf 7 and securely anchored upon the opposite side of said leaf, as at 18.

In operation leaves 7 and 8 are extended to occupy the same plane, atwhich time arms 1 1 and 12 and the part (1 of plate 10 will swing andmake contact with a part of the outer side of leaf 7, and the arms of the swivel are then forced to a transverse position with reference to arms 11 and 12, thereby confining these arms from any movement. The grain-door is then placed within the car so that the free end of leaf 7. Fig. 1, will make surface contact with one of the vertical posts or jambs of the car-door, as at 3, the portionf, Fig. 4, of plate making surface contact with the plate 10 aresupported by the vertical wall of I the car the arms 11 and 12 are in a measure V forced inwardly, and therefore operate as supporting means to assist in sustaining leaf .7, and theioutward pressure of grain in one part ofthe car is thereby utilized to counter-- balance the outward pressure of grain com- 1 ing upon leaf 7 in another part of the car,

and it is evident that if leaf 8 is constructed wider than shown the sustaining effect of arms 11 and 12 will be increased correspondingly in the manner described. By employing the construction as shown the hinges, hinge connections, and locking means may be less strongly made and the entire grain- 1 door may be lighter and cheaper than is jfound in hinge-doors where the weight of v 3 grain presses equally upon the two leaves.

Leaf 7 is constructed of a greater width than leaf 8, so that the weight of grain pressing outwardly, will facilitate the outward 0 en 7 ing of arms 11 and 12 at the moment 0 unloading. Grain is generally delivered in chutes at the side of the car when unloading,

' and upon a part rotation of swivel 13 the arms 11 and 12 will be released and will swing outward from pressure of the grain.

I i If leaf 8 has a width equal, or nearly so, to

that of leaf 7, the grain will not force arms 11 and 12 outwardly, in which case these arms are used as levers at time of unloading to manually swing them outward to release the grain.

It will be noted that the portion 11 of plate 10 operates to make a closure of the seam or aperture 6, this function being to prevent es cape of grain therethrough, and arms 11 and tain it.

12 are adapted to make contact upon a sufficient outer surface of leaf 7 to properly sus The arms 14 and 15 of swivel 13 have a I central bearing-surface g, the swivel at this bearing-surface being of greater thickness than the endsh and 'i to permit the ends to overlap arms 11 and 12, and are provided with reversedly-inclined inner faces 9' and It, so as to allow these contacting ends to make effective frictional contact upon said arms 11 and 12.

What I claim as my invention is 1. In a grain-door for cars, the combination of a first leaf and a second leaf hinged at their inner edges, a reinforcing-plate rigidly mounted on the outer face of the second leaf and extended lengthwise to overlap a part of the first leaf, a fastening means secured to said first leaf adapted to engage the lengthwise-extended part of said reinforcing-plate; said first leaf being of such a width that the outer edge thereof directly engages one wall of the car when said leaves are vertically disposed and operatively placed and makes a closure of a part of the horizontal space of the doorway, said second leaf when operatively placed being of such awidth that it will make a closure of the doorway-space not occupied by said first leaf and also will extend adjacent to the opposite wall of the car a sufficient distance to cover a space greater in area than the space occupied by said second leaf of said doorway-space.

2. In a grain-door for cars, the combination of a first leaf and a second leaf hinged at their inner edges, a reinforcing-plate rigidly mounted on the outer face of the second leaf and extended lengthwise to overlap a part of the first leaf; arms formed upon the overlapping part of said reinforcing-plate on the same plane thereof and extended parallel in a manner to overlap parts of the outer surface of said first leaf, and a fastening means on said first leaf adapted to engage said parallel extending arms; said first leaf being of such a width that the outer edge thereof directly engages one wall of the car when said leaves are vertically disposed and operatively placed and makes a closure of a part of the horizontal space of the doorway, said second leaf when operatively placed being of such a width that it will make a closure of the doorway-space not occupied by said first leaf and also will extend adjacent to the opposite wall of the car a sufficient distance to cover a space greater in area than the space occupied by said second leaf, of said doorway-spac'e.

In testimony whereof I affix my signature in presence of two witnesses.
